So briefly;

I have paladin lv 9 so far and i'm focusing on +HP runes to survive for a lot longer. Although it does really help in different situations, I was wondering if going fully on +Mastery gems would be a better idea? I really don't have that much experience with 10-20 lv bracket battles so I can't really say which item enchancements are best at this lv and in the future.

If you have experience with Paladins, i'll gladly take some advice

Hp.
Your heals are already good enough, just spam rmb if not but you always need more HP against mortar/skyfire/finishing blow/inq.

If I'm lucky with forge, I think I can reach 6k hp.

Funny thing, even working with forges, runes and gear you end up with a nice amount of HP, but still in game it doesnt make much difference. Still you get randomly either one hitted to death or hitted once and running away untill something else hits you another time and kills.

Try to play naked in this case.

As a healer you don't need HP. It is your team's job to protect you and you to protect them.
If I were you, I would put gems in Mana & Mastery

HP.

Hi.

The ideal way to heal enough + Be resistant against your worst ennemies (Inquisitors + Zerks particularly ) Is to gfet at least 2200 Mastery and 5500+ HP

If you are able to enchant your stuff +5/+6 , You will need 3/4 mastery runes and 8/9 HP runes

For amulets, if you use them, i'd advice Move Speed, HP, HP regen and Mastery, to be able to be more resistant, more mobile for dodging and kiting, and get a good amount of heal.

Are the numbers from DariusKhan still uptodate? My paladin is close to equipping amulets and runes and I already thought a lot about what to use but only from theory without practical experience I can't find a good conclusion.

Amulets:
Crits don't affect heals, so only need to choose from 5 remaining.
Is attackspeed useful? I get 20% from the powder.
Is HP regen useful? Even with 5-6k HP it does not sound that effective as for zerks and tanks with 10k++.
Is movementspeed useful? Easier runing from enemies. But I have a team to protect me and take attackers away from me. Movementspeed does not prevent oneshots from backstabbing inqs while being in an unstoppable powder-animation.

Runes:
Mana and Energy would be nice to have but cannot beat HP and Mastery.
With more Mastery my heals get better, so my teams survives longer and they can take better care of protecting me.
With more HP I survive longer, so my team survives longer.
More HP makes the HP regen amulet more effective.
More Mastery makes my selfheal more effective.
Do I need HP runes? Can they prevent oneshots from critical backstabbing inqs or block-breaking powerattacks from zerks?
Do I need Mastery runes? With full HP runes I can survive better (everything?) and give uninterrupted heals which outweigh higher but death-interrupted heals.


As you can see I nearly go nuts about this topic...
I don't want someone to tell what to choose without knowing why.

Is there that one best way to play or are there maybe 2 or more possible ways? How do you fellow paladins play and why?

Use hp runes, its the best way.
